Normal Pressure Hydrocephalus: 7 Surprising Facts You Should Know

Billy Joel’s diagnosis sheds light on a misunderstood brain condition—and why early treatment (and possibly cannabis) matters more than ever.

TL;DR — Top Takeaways ☕

1. Billy Joel’s diagnosis of normal pressure hydrocephalus is bringing this lesser-known brain condition into the spotlight—and it’s more common than you’d think.

2. NPH can mimic dementia or Parkinson’s, but unlike those, it’s often treatable, especially with a brain shunt.

3. Symptoms include shuffling gait, memory issues, and urinary trouble—but early diagnosis can reverse them.

4. There’s no slam-dunk cure in a bottle, but some patients explore cannabis for symptom relief like pain, mood, or sleep.

5. Science is still catching up, but cannabis shows promise in related brain and inflammation conditions—just don’t fire your neurosurgeon yet.

Part 1: Wait, What Is Normal Pressure Hydrocephalus?

So here’s the thing: normal pressure hydrocephalus—or NPH—is one of those conditions that sounds made up by a medical drama writer who forgot their character already had Alzheimer’s. But it’s real. And surprisingly common in older adults.

It’s a disorder where cerebrospinal fluid (CSF) builds up inside the brain’s ventricles (those internal channels that act like tiny plumbing tubes). You’d think that would jack up pressure inside the skull, but in NPH, the pressure remains—well, normal. Hence the name. Mysterious? Yes. Misleading? Also yes.

This backup of fluid causes the ventricles to swell, squishing the brain in all the wrong places. That squishing? It can lead to a very specific (and very odd) triad of symptoms:

• A slow, shuffling gait that feels like your feet are stuck to the floor.

• Cognitive slips that look suspiciously like dementia (but aren’t).

• Urinary urgency or incontinence that shows up without a UTI in sight.

It’s often misdiagnosed as Parkinson’s, Alzheimer’s, or just plain “getting older.” Which is heartbreaking, because unlike those degenerative diseases, NPH can be reversed in many cases—if caught in time.

So if you’re losing your keys, your footing, and your dignity all at once? It might not be aging. It might be fixable.

Next up in Part 2, I’ll cover what’s actually treatable about this condition, why Billy Joel might be lucky, and how a shunt can change everything—along with what (if anything) cannabis might bring to the table.

Part 2: Why Billy Joel Might Be Lucky

If there’s ever a weird moment when a celebrity diagnosis feels like good news—it’s this one.

Billy Joel has just been diagnosed with normal pressure hydrocephalus, and while “brain surgery” and “late-life neuro symptoms” don’t sound like causes for celebration, here’s the twist: NPH is one of the few neurological disorders that can be reversed. Not slowed. Not managed. Reversed.

Treatment usually involves installing a ventriculoperitoneal (VP) shunt—a tiny, programmable tube that drains the excess fluid from the brain into the abdomen where it’s absorbed like nothing happened. Think of it as an internal faucet that turns off the cerebral flood.

And it works. In the right patients:

• Over 80% see improvement in walking—which is often the most obvious and debilitating symptom.

• Cognitive clarity can return, especially if the procedure happens early.

• Even urinary issues improve in more than half of cases.

Of course, it’s not magic. There are risks: infection, overdrainage, device malfunction. But the upside is significant, especially if the condition is caught early—before permanent brain damage sets in.

So if you’re Billy Joel? You’ve got access to top-tier neurosurgeons, likely caught it in time, and may soon be walking better, thinking sharper, and playing Madison Square Garden with more bladder confidence than ever.

Part 3: Enter Cannabis (Cautiously)

Now here’s where things get a little hazy. Not because of the weed—because of the science.

There’s no direct clinical trial showing that cannabis treats or reverses normal pressure hydrocephalus. Let’s be crystal clear: the only proven intervention is surgical. No tincture, vape, or brownie is going to swap places with a shunt.

That said, it’s worth asking: could cannabis help with the symptoms? Maybe.

In some patients, cannabis seems to ease chronic pain, anxiety, and sleep disturbances—common tag-along symptoms of NPH. There’s also emerging research suggesting cannabinoids like CBD and THC might have anti-inflammatory and even neuroprotective effects in other brain conditions (like multiple sclerosis, epilepsy, or traumatic brain injury).

So if you’re a patient managing stiffness, sleeplessness, or post-surgical stress after a shunt procedure, cannabis might have a role to play as an adjunct. Not a replacement. Not a cure. But a tool. Like Tylenol, only moodier.

Of course, anyone considering cannabis—especially with a neurosurgical history—should do so under the guidance of a knowledgeable physician. Not all cannabis is created equal. And not all brains like it.

Up next in Part 4, I’ll look at why this condition is so often misdiagnosed, why that matters, and how to talk to a doctor without sounding like you’re quoting Reddit.

Part 4: The Misdiagnosis Trap (a.k.a. How to Not Get Written Off as Just Old)

Here’s the cruel part: normal pressure hydrocephalus is wildly underdiagnosed.

It’s estimated that up to 10% of people diagnosed with dementia or Parkinson’s may actually have NPH. That’s millions of people globally walking around with a reversible brain condition—being told it’s irreversible.

Why? Because NPH impersonates aging so well. Slower gait? Must be arthritis. Memory slips? Hello, Alzheimer’s. Sudden urge to pee? Welcome to your 70s. It all blends into the same fog of “normal decline,” and unless someone notices the pattern—the full trifecta of gait, cognition, and incontinence—NPH doesn’t even make the list of possibilities.

Even if it does, the testing isn’t exactly… glamorous. It often requires a high-volume lumbar puncture (where they drain fluid from your spine and then see if you walk better—like a neurological before-and-after photo shoot). MRI scans, tap tests, and walking assessments come next, sometimes with mixed results. And let’s be honest: it’s not easy to convince a tired senior (or their tired adult children) to pursue a second, third, or fourth opinion when everyone’s just trying to get through the week.

But here’s the truth: the earlier NPH is diagnosed, the better the outcome. So if your loved one suddenly walks like they’re wading through mud and can’t remember the dog’s name but still does the crossword, speak up. Ask about NPH. Be the squeaky wheel. It might just be the thing that gets them back on their feet. Literally.

Part 5: So Where Does This Leave Us?

If you’re feeling whiplash from reading this—relax. You’re not alone. The story of normal pressure hydrocephalus is, by nature, a little disorienting. A condition that looks like dementia but isn’t. A surgery that sounds scary but works. And a treatment landscape where cannabis may help—but not in the way Instagram says it will.

Billy Joel’s announcement pulls this whole conversation into the mainstream. And that’s a good thing. Because the more people who recognize NPH, the more people who might catch it in time. And maybe—just maybe—someone you love who’s been quietly fading could start to come back.

With a little clarity. A steadier step. And possibly, with a supportive cannabis regimen that’s thoughtful, guided, and aimed at easing the ride.
